Two interesting projects Inverer the-PIC and Terra PIC terra abviously with pets or aquarium cabinet temperature of the light feeding control enables Inveria the air control may be associated with exactly can not bring my project to publish reasons CCS prepared with source code and Orcad files that I did not understand my PIC Programming could be useful for dealing with our friends. Isis also came prepared with layers of simulation files in the library’s code a project that will benefit in every way
This project, which I have served as project purpose career consists of a controller for automatic terrariums, is thought to regulate temperature, humidity, hours of light and water to create a perfect microclimate for any reptile and with a few adjustments can be adapted as a controller for small greenhouses
The project will include the schematic design and pcbs, as well as the source code in C for the PIC 18F2520, documentation and a couple of videos of the system in operation.
